restart

The gage can read differently when the car is down or up in the front, obviously the fuel tilts with the car and the float level in the tank changes somewhat. Any cel on, has it been scanned to look at fuel trims and 02 activity, what is the actual mileage and driving conditions, and local air temps? Not enough is provided here. Checked for any fuel in the hose to the fuel press. regulator?

Very hard to understand your sentence phrasing. Do what has been suggested for starters, and get an actual mpg figure.

Sorry about my writing, I was trying to rush the message. But i live in cleveland so the weather could be 70 today snow tommarow. The suggestions you've mention to me make sence mainly having my fuel pressure checked. Also Driving i usually get to my destination with out the Temp engine gauge reaching the middle. This inculdes a 2 mile street drive w/ one minor hill. next an up hill on ramp and a 6 mile freeway drive to an exit incline ramp. Followed by an 5 mile drive. This drive has little stoping and a combination of 13 miles. Iv'e researched the mileage and 22 is the freeway/street rating. I repeat that same trip home but it's more a a down hill trip. Today i burned a hole block of gas, which i assume is roughly 2 1/2 gallons. So correct me if im wrong but im think im lossing alot of gas!. The guage shows i burn more on the way back then there about 3/4 more:uhoh: .I thought maybe the car thinks it has more gas then it does then as i drive it readjusts. But this is to big of a swing. The information is a typical day of driving.As mention eairler on a full tank i can get about 3 or four days out of 1 block which isn't good. Other than that the car runs great but i think it's just running rich.Plz read this and reply with more things to check! thank you for ur effort

Again, fill it up, then put some miles on it refill it and do the math, you should also scan it and make sure it comes up to temp, remember it will not go to overdirive till the trans fluid is warm also, my 2003 Lesabre gets about 18 mpg under these conditions then 29 on a long trip.
